This paper presents the systematic finite element analysis to investigate the different binder effects in sand mold casting in cooling of Aluminum alloy. Generally the mold materials controls smooth, uniform and complete filling of the cavity by the molten metal. In this study three different types of binding materials namely clay, molasses and oil were used as binding material of sand. Bottom gating system is used for its low gas entrapment and less surface defect characteristics. Experimentation was carried out for the different binders and computational analysis was also done for selecting the best binder. Best binder was selected based on cooling rate. A CAD model was generated using Solidworks and a fluid flow analysis was done accordingly to verify the effects. Simulation parameters and boundary conditions were extracted from an actual experimental condition. Both the experimentation and CFD simulation shows that clay is the best binder where cooling is more rapid. [ABSTRACT FROM AUTHOR] |
